To all 'whom t may Concern:

Be it'known that I, ELnorn P. FARUM, a citizen of the United States, anda resident of Oakland, county of Alameda, and State of California, haveinvented a new and useful Lock for Slidable Windows, of which thefollowing is agspecification.

My invention relates to a lock or clamp for preventing the rattle ormovement of slidable, windows, especially of the class which are adaptedfor use in connection with the sides of the enclosed type of body of anautomobile.

An object of the'invention is to provide a lock for slidable windows ofthe character described which can be constructed and assembled for themost part directly on the sash before the latter is positioned'i'n thewindow frame, thus obviating to a great extent the necessity of workingunder the difcult conditions such as obtain when the most. of theConstruction and assembling must be done the pockets .of the top andbody of the automobile. s

Another object of the invention is to pro-k vide a lock for a slidablewindow which will automatically lock or clamp the window sash as itreaches, fthe limit of its movement in one direction, and which will beautomatically disengaged or released upon the initiation of thereturning movement of the sash.

The invention possesses other objects and features of advantage, l' theforegoing, will b e set forth in the following description of thepreferred form of my invent-ion which is illustrated in the drawingsaccompanying and forming part of the specification. lt is to beunderstood that l do not limit myself to the showing made by the saiddrawings and description, as l may adopt variations of the preferredform within the scope of my invention as set'forth inthe claims.

Referring to said drawings: Fig. 1, is a side elevation of the upperortion of an enclosed car provided with thesliding windows and lock ofmy invenf` tion, parts of the struct-ure being broken away to disclosethe ordinarily hidden portions more clearly.

V Fig. 2, is a transverse vertical section of oneside of the body, theplane of section being indicated by the line 2-2 of Fig. 1.

' Fig. 3, is ahorizontal section of one side some of which, with of thebody as seen when looking upwardly from just below the track.

-Brieiiy'expressed my invention cooperates with a set of window Vsashesarranged in a suitable frame between the l forward and rear end of thebody top and between 7the upper and lower edge thereof. Means areprovided, which include a pivote'd bar "and a stop, for lockinga sashagainst movement as it reaches the extent of its movement in onedirection. Upon initiating the return movement of the sash apsecondstopis 'encountered which acts to releasethe sash Afrom its lockedposition so that vit may be moved freely. Means are included foradjusting the degree of tension tending to retain the sashL in itslockedk position.

A detailed description of my invention follows:

The body 2, my apparatus is embodiechis provided in one or 4more of itssides with an opening 3, which extends downwardly from the lower edge ofthe top 4, to the upper edge of the doors 5, and between. the permanent"winglot'y 6, and the windshield?4 The sides' ofthe opening are providedwith what may' be termed, a frame 8, Awhich comprises walls'. i9 andpockets 11 and 1 2, in 'which' are slidably disposed a "set of windowsashes y13 and 14. The pocket 11 is formed inside of the permanentwindow 6 and serves to enclose the slidable sashes 13 and 121 when .theyare in their rearwardjor open position. The pocket 12 is formed in thelower edge of the top and extends longitudinally' for `practically thefull length of the top.k Fixed in the pocket 12 andspaced from the sidewalls 9 thereof is a track member 16 provided on its opposedsides with4grooves 17 and 18 in which engage hangers 19 and 21 respectively andfrom whichdepend the 'sashes` 13 and 14: respectively. Thesash 13', whenin its forward or closed position, is arranged to errgage the forwardend of theopening' ja'nd is; prevented fromlswingin'g outward Vby meansof a suitable guide 22 ,formed .on 'the top`A of thedoors. The Vsash 14when in its forward position is adapted to engage the spacel between thepermanent window 6' and the sash 13 when the latter islextended. n Thesash 1li is prevented from being swungjtransversely by means of theguide 23 also preferably formed ony thedo'or. As shownin of theautomobile, in which Y Fig. 1 suitable handles 24 and 26 may be providedon the sashes for readily sliding them longitudinally in the frame.

Means are provided for locking or clamping the sashes against movementwhen they assume their forward or closed position. Arranged in thepocket 12 and between the top ofthe sashes and the bottom of the trackmember are longitudinally disposed bars 27 and 28. The bars areconnected by sets of parallel links 29 and 31 to the sashes 13 and 14respectively. lV hen a sash is not quite in its extreme forward positionthe' links and bar with which it is associated assume the collapsedposition shown in connection with the intermediate sash 14 in Fig. lofthe drawings; however, when the sash approaches its vforward position,the bar strikes against one of the abutments 32 and 33 which are in thepath of the bars 27 and 28 respectively whereby the bar is forced up`wardly into tight engagement with some part of the frame, such as thebottom of the track member'upon the continuation of a slight forwardmovement and thereby practically arresting further movement of the sash,and preventing any rattle.

Means are provided for varying the amount of tension that will obtainbetween the bar and track for a given movementof the sash preparatory tobeing locked. Extending preferably from the bottom of the trackmember'and adapted to overlie the central portion of the sashes when thelatter are in their forward positions, are screws 34 and 36 disposed inthe vertical plane of the sashes 13 and 14 respectively. In order tovary the said tension it is merely necessary to screw the bolt inwardlyor outwardly. inward movement of screw serving to relieve the tension,whereas outward movement will increase the tension.

Means are also provided for causing the locking mechanism to beautomatically reL leased or collapsed upon initiating the returnmovement of the sash. Fixed to the track y. the stops 27 and 28 so andaligned with the bars are stops 37 and 38 which lie just back of thebars when the sashes are in theirextreme forward position. The stops 37and 38 are much shorter than that the bars clear the former during theforward movement of the sashes or in other words, while the bars arecollapsed; however, when the bars are extended as shown in connectionwith sash 13 of Fig. 1, the stops 37 and 38 will lie th directly in thepath of the bar with which it is aligned, thereby causing the bar tomove downwardly as soon as the returning movement of the particular sashis commenced.

It will be noted that when the bar is l moved from its collapsedposition toits extended position, the pivotal point 41 be,- tween thelink and the bar moves from one side to the opposite side of a verticalline which would intersect the pivotal point 42 of the link and sash,and therefore means are provided for limiting the extendible movement ofsaid links after the point 41 has passed a short distance beyond saidline, so that the bars may be prevented from collapsing and therebyinadvertently releasing the sash. Projecting preferably from the bottomof the track and engaging inclined recesses 48 and 44 of the sashes 13and 14 respectively are adjustable pins 45 and 46. When the bars are intheir extended position the pins preferably engage the shallow portionof the recess and when the bar is col lapsed the pins are adapted torest in the deep portion ofthe recess.
